WASHING-MACHINE Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed August 12, 1908. Serial No. 448,210.

To all whom it may concern:

Be it known that I, ALBERT A. DAY, citizen of the United States,residing at borough of Brooklyn, in the county of Kings, city and Stateof New York, have invented certain new and useful Improvements inWashing- Machines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention consists in the novel features hereinafter described,reference being had to the accompanying drawings which illustrate oneform in which I have contemplated embodying the invention and a slightmodifica tion thereof and said invention is fully disclosed in thefollowing description and claims.

Washing machines, such as are used in large steam laundries, areordinarily provided with mechanism for reversing automatically thedirection of rotation of the revoluble cylinder or inner casing after afew revolutions in either direction in order to prevent the balling ofthe clothes under treatment; and the sudden arresting of the cylinderand the sudden starting of it in the opposite direction, produces aconsiderable stram upon the mechanism, and further the construction ofsuch mechanism as will render this action automatic, adds to the expenseof the machine and the difliculty of keeping it in working order.

One of the objects of my invention is, therefore, to provide a washingmachine in which the rotatable cylinder is rotated at all times in thesame direction; and in order to provide for the proper agitation of theclothes and the application thereto of the water and cleansingmaterials, the interior of said rotating cylinder is provided, throughthe central portion, with a plurality of interiorly projecting blades orshelves; which while extending in a general direction around theinterior are arranged in a zigzag manner, so that the clothing, as it iscarried up on the rising side of the cylinder, will fall from one zigzag portion to another, and so on always toward the bottom of thecylinder. The end portions of the cylinder are provided internally withbuckets so arranged as to carry up quantities of the water or liquidcleansing material, and said buckets have their bottom portions inclinedtoward the axis of the cylinder, so as to discharge the liquid withconsiderable force and in considerable quantity my present invention.

upon the clothes as they descend from one of the zigzag blades orshelves to another, thereby facilitating the elimination of dirt, etc.

In the accompanying drawings, Figure 1 represents a vertical sectionalview taken longitudinally of a washing machine embodying Fig. 2represents a vertical transverse section of the same on line 22 ofFig. 1. Fig. 3 represents a vertical transverse section of the machineon line 33 of Fig. 1, looking in the direction of the arrow. Fig. 1 is avertical longitudinal sec tion of a slightly modified form of themachine, and Fig. 5 is a sectional detail of part of the constructionshown in Fig. 4.

Referring to the drawings, 1 represents the exterior casing of themachine which is preferably cylindrical, although it may be maderectangular or of other polygonal form in cross section. This casing issupported upon suitable legs as indicated at 2, and is provided with a.suitable door, 3, by means of which access may be had to the interior.The casing 1 is also provided with both a discharge pipe 4 and an inletpipe 4* having therein suitable cut off valves or cocks 5, 5 for drawingoff and admitting the liquid contents when desired. An overflow pipe 49is also provided as shown.

Within the casing 1 is the rotating cylinder 6, supported therein so asto be capable of rotation and here shown as provided at each end with aplate 7 having a trunnion 8 engaging a bearing 9 in the end wall of theouter casing 1. One of the trunnions 8 is extended beyond the bearingand provided with fast and loose pulleys 10, 11, as shown, or othersuitable means for applying power to eifect the rotation of the cylinder6.

The cylinder 6, in the form of my invention shown in Figs. 1, 2 and 3,has its centra portion provided interiorly with a series of inwardlyprojecting blades 12, each of which extends entirely around the interiorof the cylinder, but in zigzag manner, thus providing a plurality ofangularly disposed and opposed portions 13, 14 and as shown in Fig. 1.The angular portions 13 of all the blades are arranged parallel to eachother and the angular portions 1 1 are arranged in a similar manner,although this is not essential. The end portions of the cylinder at eachend are provided with a plurality of buckets, 15, extending from thehead or end of the cylinder inwardly and having their bottom portions,

16, inclined from the ends of the cylinder 6, toward the longitudinalaxis of the cylinder, so as to discharge their contents in a directiontoward the central portion of the cylinder. The inner ends of thesebuckets are preferably entirely open, as shown in 1 and 3, so as toallow the water to be discharged therefrom with considerable force andin large volume; but they may be par tially closed. The cylindrical wallof the cylinder 6 throughout the central portion which is provided withthe zigzag portions of the blades, is also provided with perforations17, to permit of the free access of the water or cleansing liquid fromthe outer receptacle 1 into the interior of the cylinder 6. The cylinder6 is also provided with. a suit able door 18 which can be opened whenbrought into alinement with the exterior door 3, to give access to theinterior and the doors 18 and 3 are provided with any suitable securingmeans as desired.

In the operation of the machine, the receptacle 1 and cylinder 6 arefilled to a desired level with water or other cleansing liquid, in theusual manner, the liquid level being prelerably below the plane of theaxis of rotation of the cylinder 6. The clothes or other articles to becleansed are charged into the cylinder 6 through the doors 3 and 18,which are then closed and secured in any desired way, and the cylinder 6is rotated continuously in one direction. As the cylinder 6 rotates theangular blades 13, 14, on the rising side will tend'to carry portions ofthe articles upward and these articles will slide by gravity down saidinclines from one to another, being arrested continually and havingtheir direction of descent altered as they slide and 1111- pact from onezigzag portion to another. Simultaneously the buckets 15 at each end ofthe drum which will fill with liquid while submerged therein, will risewith the rotation of the cylinder and as soon as they pass above theliquid level will begin to discharge their contents with considerableforce and volume upon the articles, thus facilitating their zigzagdescent along the blades 13 and 14. The impacting or bumping action.which the articles of clothing receive from the zigzag blades and thecoincident sensing of the cleansing liquid upon them from the buckets15, causes the dirt, etc, to be-rapidly removed, and greatly facilitatesthe cleansing of the articles.

In Fig. 4 I have shown a slight modification of my invention in which 1represents the exterior casing and 6 the rotatable cylinder mountedtherein, as before described. In this case the central portion of thecylinder is provided with two or more circular series of inwardlyextending blades 13 and 14, the blades of one series alternating withand being oppositely inclined to the blades of adjacent series. The endportions of the cylinder are provided with buckets 15 simi lar to thebuckets 15, previously described, having inclined bottom portionsinclining toward the axis of the cylinder, but having at their dischargeends a retaining wall 19 provided with one or more discharge apertures20 of less aggregate area than the end of the bucket, so as to retainthe liquid longer as the buckets rise and discharge it therefrom moreslowly than where the entire inner end of each bucket is open.

The operation of the apparatus shown in 7 Figs. 1 and 5 is practicallythe same as that previously described. In all cases the inner wall ofthe bucket which extends into the interior of the cylinder has its innerend or corner beveled and inclined as indicated at 21, Fig. 1, so as topermit any articles of clothing which might otherwise catch thereon, toslide off into the center of the cylinder.

What I claim and desire to secure by Letters Patent is 1. A washingmachine provided with a retating cylinder having portions between itsends provided with inwardly projecting blades disposed angularly withrespect to each other and its end portions provided with buckets adaptedto discharge in a direction towards the said blades, substantially asdescribed.

2. A washing machine having a rotatable cylinder provided interiorlywith a plurality of blades projecting inwardly h'om the cylinder walland disposed angularly with respect to each other and an annular seriesof buckets at each end of the cylinder having bottom portions inclinedtoward the axis of rotation of the cylinder, said bucketshaving'discharge apertures at their inner ends, substantailly asdescribed.

3. A washing machine having a rotatable cylinder provided interiorlybetween its end portions with inwardly projecting blades ex tending inzigzag form around the interior, the zigzag portions of said bladesbeing substantially parallel to corresponding portions of adjacentblades, said cylinder having an annular series of buckets at each endhaving their bottom portions inclined toward the axis of rotation of thecylinder and being provided with discharge apertures at their innerends, substantially as described.

In testimony whereof I arfix my signature, in the presence of twowitnesses.
